Json Nested Struct

[armanriazi]

👋 Test can not deserialized with json macro I do not know how I handle it?

#[cfg(test)]
mod tests {
    use std::fs;
    use serde_json::{json};
    use serde::{Deserialize, Serialize};
    
    #[derive(Debug,Clone,Deserialize,Serialize)]
    pub struct Transactions {
        pub puts: Transaction
    }
    #[derive(Debug,Clone,Deserialize,Serialize)]
    pub struct Transaction {
        pub inputs: Vec<Value>,
        pub outputs: Vec<Value>,
    }
    #[derive(Debug,Clone,Deserialize,Serialize)]
    pub struct Value {
        pub to_addr: String,
        pub value: u64,
    }
    #[derive(Deserialize, Debug)]
    struct User {
    fingerprint: String,
    location: String,
    }
    use super::*;
    #[test]
        pub fn sample_trx_json_data_block2_from_file(){
            let file_contents = fs::read_to_string("sample.json")
            .expect("Something went wrong reading the file");
            //dbg!(json!(&file_contents));
            //let  js=json!(file_contents);
            let s="\"transactions\":[{\"transaction1\":[\"inputs\":[{\"to_addr\":\"Alice\",\"value\":\"47\"},{\"to_addr\":\"Bob\",\"value\":\"3\"}],\"outputs\":[{\"to_addr\":\"Alice\",\"value\": \"46\"},{\"to_addr\":\"Bob\",\"value\":\"1\"}]}],\"transaction2\":[{\"inputs\":[{}],\"outputs\":[{\"to_addr\":\"Alice\",\"value\":\"0\"}]}],}]";
            let ss="{\"transactions\":[{\"transaction1\":[\"inputs\":[{\"to_addr\":\"Alice\",\"value\":\"47\"},{\"to_addr\":\"Bob\",\"value\":\"3\"}],\"outputs\":[{\"to_addr\":\"Alice\",\"value\": \"46\"},{\"to_addr\":\"Bob\",\"value\":\"1\"}]}],\"transaction2\":[{\"inputs\":[{}],\"outputs\":[{\"to_addr\":\"Alice\",\"value\":\"0\"}]}]}]}";
            //let ar=js.as_array().unwrap();
            
            let j = "
            {

                \"location\": \"Menlo Park, CA\"
            }";
    
        //let u:Transactions  = serde_json::from_str(&file_contents).unwrap();  //=>Error with Transactions  Nested Struct
        //let u:serde_json::Value  = serde_json::from_str(&j).unwrap(); //=>Error with Value Json Model
        let u:User  = serde_json::from_str(&j).unwrap();
        println!("{:#?}", u);
     }
}

Please provide a minimal example, it will be much easier to help you. Especially since your test references an external file that we don't have.

If this is still an issue, please take your question to any of the resources shown in https://www.rust-lang.org/community. Serde is one of the most widely used Rust libraries and plenty of people will be able to provide guidance about it.
